Description

Technical Field

[0001] This utility model relates to the technical field of incineration gas treatment equipment, specifically to an environmentally friendly waste incineration gas treatment device. Background Technology

[0002] During the combustion process, due to the complexity and unevenness of the waste composition, many different chemical reactions occur. The resulting flue gas contains not only excess air and carbon dioxide, but also components that pose direct and indirect harm to human health and the environment. Based on the nature of the pollutants, they can be divided into four main categories: particulate matter, acidic gases, heavy metals, and organic pollutants.

[0003] In the initial stage of incineration gas treatment, particulate matter is often treated. However, incineration gases are generally at high temperatures, so they are usually cooled before filtration. Some existing heat exchange equipment is not suitable for heat exchange of incineration gases, so they are usually directly injected into water for cooling. However, this method generally results in high energy loss, and high-temperature wastewater treatment is also relatively energy-intensive. Utility Model Content

[0007] Furthermore, the heat exchange structure includes an exhaust gas pipe connected to the high-pressure intake pipe. The exhaust gas pipe is provided with an internal cooling pipe and an external cooling pipe inside and outside, respectively. The internal cooling pipe is provided with a first intake pipe and a first exhaust pipe at both ends, and the external cooling pipe is provided with a second intake pipe and a second exhaust pipe at both ends, which facilitates efficient heat exchange operations.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figure 1-4 An environmentally friendly waste incineration gas treatment device includes a filter and dust removal chamber 1 and a heat exchange chamber 2. A high-pressure air inlet pipe 4 is located on the top outer side of the heat exchange chamber 2. The high-pressure air inlet pipe 4 has a gradually narrowing inlet space to ensure the rate of subsequent gas passage. An exhaust fan can be added as needed. The high-pressure air inlet pipe 4 extends into the heat exchange chamber 2 and is equipped with a heat exchange structure 3. As shown in the figure, the heat exchange structure 3 is a top-down coil structure, which effectively prevents condensation and waste residue accumulation. The heat exchange structure 3 includes an exhaust gas pipe 21 connected to the high-pressure air inlet pipe 4. The exhaust gas pipe 21 has an internal cooling pipe 22 and an external cooling pipe 23 located inside and outside, respectively. The internal and external cooling pipes 22 and 23 are used to simultaneously exchange heat inside and outside the exhaust gas pipe 21, which can ensure high efficiency of heat exchange. The internal cooling pipe 22 is provided with a first inlet pipe 24 and a first outlet pipe 27 at both ends, and the external cooling pipe 23 is provided with a second inlet pipe 25 and a second outlet pipe 28 at both ends. The first inlet pipe 24 and the second inlet pipe 25 are provided with flow control valves 26, and the first outlet pipe 27 and the second outlet pipe 28 are provided with temperature sensors 29. That is, the flow control valve 26 is set at the inlet end and the temperature sensor 29 is set at the outlet end. The flow control valve 26 is controlled according to the temperature sensor 29, thereby controlling the flow rate of the cold air and ensuring the quality of heat exchange.

[0021] The heat exchange structure 3 is connected to an air guide pipe 5 extending to the bottom of the filter dust removal box 1. Water is injected into the bottom of the filter dust removal box 1. The air guide pipe 5 extends to the bottom of the filter dust removal box 1 and is equipped with an air distribution plate 6. The bottom of the air distribution plate 6 is equipped with multiple air outlets 7. The bottom of the filter dust removal box 1 is equipped with a drain pipe 16 and a drain valve 17. A water replenishment valve pipe 10 is provided on one side of the bottom of the filter dust removal box 1. That is, the gas after heat exchange is completed is discharged over a large area through the air distribution plate 6 and multiple air outlets 7 to ensure repeated contact between the gas and water. This allows for the adsorption of a large amount of dust particles by water. The drain valve 17 is opened to periodically discharge the wastewater, and then the water is replenished through the water replenishment valve pipe 10.

[0022] The filter dust removal box 1 has a partition plate 8 in the middle, and a partition inner cylinder 9 on the top of the partition plate 8. The partition inner cylinder 9 divides the area above the partition plate 8 into an internal air inlet chamber 12 and an external clean air chamber 11. The top of the filter dust removal box 1 has multiple exhaust pipes 15 that communicate with the clean air chamber 11. The partition inner cylinder 9 has a dust filter cylinder 13. The structure of the dust filter cylinder 13 can be set as needed. The mesh diameter of the dust filter cylinder 13 is set according to the size of the filter material. If finer filtration is required, an attached filter cloth layer can also be set to filter fine dust. The partition inner cylinder 9 has a support rod 14 located outside the dust filter cylinder 13. The support rod 14 can support the dust filter cylinder 13 during operation. After the gas is adsorbed by water, the fine particles are filtered through the dust filter cylinder 13 and then discharged through the exhaust pipe 15.

[0023] The top of the filter dust removal box 1 is equipped with a drive motor 18, and the bottom power end of the drive motor 18 is equipped with a rotating shaft 19 extending to the outside of the inner cylinder 9. The rotating shaft 19 is equipped with a cam 20. The dust filter cylinder 13 performs filtration, and dust can be easily adsorbed on the inside of the dust filter cylinder 13. By driving the rotation of the rotating shaft 19 and the cam 20 driven by the drive motor 18 to strike the dust filter cylinder 13, the dust particles attached to the inside can be shaken off.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
